Dear wapirc-- I saw a car with the same symptoms as your 2002 Chrysler 300M in the movie "Close Encounters of the Third Kind." But, I doubt that flying saucers are your problem. You obviously have an electrical problem and need a hands on diagnosis. These problems may be very minor, but the require an experienced technician to pinpoint and repair them. Take it to a mechanic you can trust. Good luck from Bovan.

Sometimes all the lights will come on and stuff will go crazy , when the charging system stops working.
Check and see if the alternator is working properly.
When the voltage drops due to not charging , warning lights will come on for all sorts of things, this happens when relays cannot be activated due to low volts and the systems computers will turn on lights indicating problems .

i have the same problem with this in my 2004 300m. can any one tell me what the problem is. it happens while driving and it happens at night while the car is sitting there, if i dont catch it it kills the battery. can any one help me.

Same problem 2000 300M, replace the light switch, meanwhile, take or turn the light switch OFF the "AUTO" selection. you will have to use it like the old days, turning them on and off, until the switch is replaced

Dear JW49 - have you ever SEEN the battery in a 300M? I can't find it. I also suffer from random light flashings, seats not warming, etc. If it starts honking on its own I'm leaving it on the side of the road.

Ive seen and heard of 2 problem areas. 1- check the ground from the engine to the firewall and the ground from the battery to the chassis. 2- when the problem occurs turn the key slightly backwards and see if the problem goes away. Often times if you have a number of keys on your key chain it causes excessive wear in the ignition switch by pulling down on it and it losing contact inside the switch.

Hi I have a Chrysler 200 2013 when turn on air or
heat there's a loud clicking last for 20
seconds.sound coming from behind glove
box.even if car isn't on this noise will still run
what is it.?
Another problem I have only at night when lights
are on the dash lights radio .clock gear .light
flicker from hi to low constantly. I think it's the
handle for signs lights has a short.

I own a 03 Chrysler 300m and today I went out to my car
and my headlights were flickering on and off like the
alarm was going off. When I left work, I turned the car on
just fine but the headlights were still flickering on and off.
Now there's a loud grinding noise coming from the
passenger side of the engine when I accelerate. Anybody
know what this is!?,

Is the grinding noise present when sitting still
and simply reving the engine? When you're
driving and let the car coast in neutral is it still
present or only under acceleration? Considering
the two problems could be linked, I'd look at the
alternator. However it's possible they are
separate issues.

it rarely illuminates when the headlamp come on. I believe that it should be a bad or dirty relay contact. This is why I would the schematics to track the devices in the circuit.
Thanks for your assi...

I was driving and my radio just went off all the lights on the dash came on my
windshield wipers just stopped working and my turn signals was blinking faintly but my
car was driving just fine, so i ...
